《springcloud学习》十 Springcloud整合consul作为注册中心

1.简介

consul是一套开源的分布式服务发现和配置管理系统，用go语言开发，raft协议，提供图形界面管理

2 window环境搭建consul注册中心

下载地址：https://www.consul.io/

下载window版本，解压后，可得到一个consul.exe

通过cmd进入，该文件夹目录

cmd>>>d:

cmd>>>cd /consul_1.5.2_windows_amd64

启动consul命令

consul agent -dev -ui -node=cy

通过http://localhost:8500访问图形界面

   注意：如果需要外面的电脑也能连上该配置，需要修改配置127.0.0.1为本地ip的地址

3 consul实现服务注册和发现

需要导入父模块依赖，具体查看之前的博客

 3.1 pom.xml 

   <!-- SpringBoot整合consul客户端 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-consul-discovery</artifactId>
        </dependency>
    </dependencies>

3.2 application.yml

###会员服务的端口号
server:
  port: 8002
###服务别名----服务注册到注册中心名称
spring:
  application:
    name: zk-member
  cloud:
    zookeeper:
      #注册到zk的地址
      connect-string: 127.0.0.1:2181

3.3 controller类

package com.fqyd.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Description：
 * Author: wude
 * Date:  2019/7/10 16:44
 * Modified By:
 */
@RestController
public class MeberApiController {
    @Value("${server.port}")
    private String port;

    @RequestMapping("getMember")
    public String getMember() {
        return "this is member!端口号为：" + port;
    }
}

3.4启动类

package com.fqyd;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient   //如果服务注册是consul或者zk，可以使用该注解
public class SpringcloudZkMemberApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringcloudZkMemberApplication.class, args);
    }

}

3.5效果

上面提供的代码是提供者的代码，消费者的代码可以把zk+springcloud博客，对应的代码修改一下就可以
